Product Information
Route-Side Product Positioning
Inline splice point for aerial fiber routes
Use this closure when the cable route needs a protected joint, branch preparation or reserve tray capacity, but the site does not require a full fiber distribution box with adapter ports.
The housing format keeps the splice area inside a sealed shell while leaving cable entry and exit positions grouped at the end of the closure for route continuation.

- End-face layout shows three cable entry positions
OSP Problem It Solves
Route Continuity
The 3-in / 3-out port plan helps technicians manage incoming, outgoing and spare cable directions along an aerial route without changing closure style.
Tray Expansion
The closure can be configured with up to four splice trays, making it easier to reserve space for later fiber counts or staged network work.
Cable Core Fixing
Strength-member fixing points hold the cable core mechanically so splice trays are not used as the load-bearing part of the installation.
Cable Port and Tray Planning
- 1Assign the route.
Decide which ports are used for main cable in, main cable out, branch cable or standby cable. - 2Match cable diameter.
Use the listed Φ8 mm and Φ13 mm cable port references when checking field cable compatibility. - 3Fix the strengthen core.
Secure the cable core before routing loose fibers into the tray area. - 4Load trays by circuit.
Separate fibers by route, cable direction or customer handoff to reduce later maintenance mistakes. - 5Protect the gasket line.
Keep the cover and bottom sealing surface clean before closing the housing. - 6Record the splice map.
Mark tray number, fiber color sequence and cable direction for handover documentation.

What Makes This Closure Different From a Distribution Box
Typical Use Cases
Feeder Cable Joint
Protects splices where a feeder cable must continue along the route after repair, extension or construction handoff.
Aerial Route Branch Point
Supports incoming and outgoing cable directions while reserving additional ports for branch or future cable paths.
FTTx Outside Plant Section
Can be used before access distribution points when fibers need to be organized, spliced and protected in the field.
Maintenance Replacement
Useful when replacing an older inline closure and the project needs a compact housing with clear tray capacity and cable port references.
Field Installation Control Points
| Checkpoint | Field Reason | Recommended Confirmation |
|---|---|---|
| Closure orientation | Wrong orientation can make cable routing or future access difficult. | Plan the opening side and route direction before hanging the closure. |
| Cable diameter | Port size must match the actual outside cable diameter. | Confirm Φ8 mm and Φ13 mm port use with the cable schedule. |
| Strength member | Mechanical load should not transfer to bare fibers or splice sleeves. | Fix the cable strengthen core with the provided fixing parts. |
| Tray loading | Mixed route fibers make troubleshooting slower. | Assign trays by cable direction, fiber group or construction phase. |
| Seal cleanliness | Dust or debris at the gasket can reduce sealing reliability. | Inspect the silicone gasket area before closing the cover. |
| Handover record | Future work depends on accurate splice mapping. | Record tray number, fiber color code and cable port direction. |
RFQ Information for GL027
For accurate quotation, send the cable diameter, fiber count, tray quantity, installation method and project environment. This avoids selecting a closure that fits the fiber count but does not fit the actual cable route.
| Model | GL027 Horizontal Fiber Optic Splice Closure |
|---|---|
| Required Quantity | Sample check, route maintenance stock or project batch |
| Fiber Count | Actual splice count and reserved fiber count |
| Tray Requirement | Number of splice trays needed, up to 4 pcs according to the data sheet |
| Cable Diameter | Confirm cable OD against Φ8 mm / Φ13 mm port references |
| Application | Aerial route, feeder joint, branch splice point or FTTx outside plant section |
| Accessories | Confirm splice sleeves, mounting accessories, labels and packing method if required |
FAQ
Q: What is GL027 used for?
A: GL027 is used for optical fiber splicing and cable protection in an outdoor inline closure format, especially where aerial route installation is required.
Q: How many fibers can this closure support?
A: The listed maximum is 96 fibers, based on up to four splice trays and 24 fibers per tray.
Q: How many cable ports does it have?
A: The data sheet lists six cable ports arranged as three in and three out, including four Φ8 mm ports and two Φ13 mm ports.
Q: Is it waterproof?
A: The listed protection grade is IP65. The design uses a silicone gasket between the cover and bottom shell for dust-proof and waterproof protection.
Q: Can it be used as a fiber distribution box?
A: It is better described as a splice closure, not a subscriber-facing distribution box. It protects cable joints and splice trays rather than presenting adapter ports for drop cable service.
Q: What information should be provided before ordering?
A: Provide cable diameter, fiber count, route direction, tray quantity, installation method, required accessories and project quantity.
